In order to further simplify the mounting, the elastic gasket 321 can be directly welded or bonded to the connection frame 4. When the connection frame 4 is connected to the boss 22, the connection frame 4 presses the elastic gasket 321 on the boss 22 to form a sealed connection. In another embodiment, the elastic gasket 321 may also be provided separately from the connection frame 4, and not directly welded or bonded to the connection frame 4 to be aligned and pressed during mounting. In another embodiment, the elastic gasket 321 can also be welded or bonded to the boss 22 or detachably connected to the boss 22.

Among them, the connection frame 4 and the boss 22 are detachably connected. It can be seen from FIG. 5 that the connection frame 4 can be fastened to the boss 22 through the through hole 41 and the boss 221, and the elastic gasket 321 is pressed between the connection frame 4 and the boss 22.
